Referring to fig. 1, fig. 1 is a schematic flowchart illustrating a method for controlling an air conditioning device based on ambient and body surface temperature and humidity according to an embodiment of the present invention.
The air conditioning equipment in the embodiment of the invention comprises an air conditioner and a humidifier.
As shown in fig. 1, the method for controlling the air conditioning equipment based on the environment and the body surface temperature and humidity comprises the following steps:
and S101, acquiring indoor environment information and temperature information of the surface of the human body through the first detection device and the second detection device.
In the embodiment of the invention, the indoor environment information comprises indoor temperature and indoor relative humidity, wherein the indoor temperature and the indoor relative humidity are both indoor real-time temperature and indoor real-time relative humidity detected by the first detection device at any moment. Alternatively, the first detection means may include an indoor temperature sensor and an indoor relative humidity sensor.

And S102, acquiring relative humidity information of the surface of the human body according to the indoor environment information and the temperature information of the surface of the human body.
Specifically, the relative humidity information of the human body surface can be obtained according to the indoor temperature, the indoor humidity and the temperature information of the human body surface.
Further, the indoor temperature, the indoor relative humidity, the temperature information of the human body surface and the relative humidity information of the human body surface satisfy:
wherein, PinIs the partial pressure of water vapor in the room, hskIs the relative humidity of the human body surface, tinIs the indoor temperature hinIs the indoor relative humidity, tskThe temperature of the human body surface.
Therefore, the relative humidity of the human body surface can be rapidly calculated according to (1).
Further, the partial pressure P of water vapor in the roominObtained from the indoor air temperature and the indoor relative humidity, namely:
and step S103, acquiring the heat balance state information of the human body according to the temperature information of the surface of the human body.
In the embodiment of the invention, the heat balance state information of the human body can be obtained according to the temperature of the surface of the human body. Wherein the thermal equilibrium state of the human body may include a first thermal state and a second thermal state. The first thermal state is an explicit perspiration state, and the second thermal state is a hidden perspiration state. The temperature information of the human body surface includes a temperature of the human body surface.
In the embodiment of the present invention, the obtaining of the thermal equilibrium state information of the human body according to the temperature information of the surface of the human body may specifically be obtained by the following steps:
and step S1031, judging whether the temperature of the surface of the human body is greater than a first preset temperature or not according to the temperature information of the surface of the human body.
Step S1032, if yes, it is determined that the human body is in the first thermal state.
And step S1033, if not, determining that the human body is in the second thermal state. In an embodiment of the present invention, the first predetermined temperature may be 34 ℃.
In the existing viewpoint of human perspiration, according to the discussion of human perspiration regulation mechanisms with different activity intensities under different environmental temperature conditions, if the temperature of the exposed surface (such as the back of the wrist) of the skin (i.e. the temperature of the surface of the human body in the invention) is higher than 34 ℃, the environment temperature is generally considered to be too high or the human body is in an activity state with higher intensity, sweat glands secrete sweat, and the human body cannot take away the redundant heat of the human body through radiation and convection ways, so that the human body is judged to be in a dominant perspiration state.
When the temperature on the surface of the human body is less than 34 ℃, generally, the human body is considered to be carried away by evaporation after the water of the human body diffuses to the body surface through the skin cuticle, the metabolic activity of the human body is more stable, and the human body can be judged to be in a recessive sweating state at the moment, so that the human body can be judged to be in a second heating state when the temperature on the surface of the human body is less than a first preset temperature.
And step S104, outputting a control signal to the air conditioning equipment according to the indoor environment information, the heat balance state information of the human body and the relative humidity information of the surface of the human body so as to adjust the running state of the air conditioning equipment. The control signals of the embodiment of the present invention include a second control signal, a third control signal, a fourth control signal, a fifth control signal, and a sixth control signal.
Specifically, when the human body is in a first thermal state, i.e., the human body is in a dominant sweating state, the air conditioning device can be adjusted by the following steps:
and S1041, controlling the air conditioning equipment to enter a first control mode according to the first thermal state of the human body.
Step S1042, determining whether the indoor temperature is less than or equal to a second set temperature.
Alternatively, the second set temperature of the embodiment of the present invention may be set to 26 ℃.
And S1043, if so, outputting a second control signal, controlling the air conditioning equipment to enter a second operation mode, and adjusting the operation state of the air conditioning equipment according to the second operation mode.
In the embodiment of the invention, the second operation mode is that the air conditioner and the humidifier are not started.
And step S1044, if not, outputting a third control signal, controlling the air conditioning equipment to enter a third operation mode, and adjusting the operation state of the air conditioning equipment according to the third operation mode.
In the embodiment of the invention, the third operation mode is that the air conditioner is set to be in a refrigeration mode, the indoor temperature is set to be 26 ℃, and the humidifier is not started.
Specifically, when the human body is in a first hot state, namely the human body is in a dominant perspiration state, and the indoor temperature is lower than 26 ℃, at the moment, the human body temperature is higher due to the fact that the human body activity intensity is high, the human body feels uncomfortable, and the indoor natural temperature is not high, so that the air conditioning equipment can be controlled to enter a second operation mode, namely the air conditioner and the humidifier are controlled not to be started. When the human body is in a first hot state, namely the human body is in a dominant perspiration state, and the indoor temperature is higher than 26 ℃, at the moment, the activity intensity of the human body is high and/or the indoor temperature is higher, so that the human body temperature is higher and the human body feels uncomfortable, therefore, the air conditioning equipment can be controlled to enter a third operation mode, namely the air conditioner is controlled to be in a refrigeration mode, the indoor temperature is set to be 26 ℃, and the humidifier is not started.
When the human body is in the second thermal state, namely the human body is in a hidden sweating state, the air conditioning equipment can be adjusted through the following steps:
step S10411, determining whether the relative humidity of the human body surface satisfies a first relative humidity condition.
The first relative humidity conditions are: the relative humidity of the human body surface is less than or equal to 25 percent.
And step S10412, if yes, controlling the air conditioning equipment to enter a second control mode.
Step S10413, determining whether the indoor temperature is less than or equal to a second preset temperature.
Step S10414, if yes, outputting a sixth control signal, controlling the air conditioning equipment to enter a sixth operation mode, and adjusting an operation state of the air conditioning equipment according to the sixth operation mode.
In the embodiment of the present invention, the sixth operation mode is: the humidifier is turned on and the air conditioner is turned off.
And step S10415, if not, outputting a third control signal, controlling the air conditioning equipment to enter a third operation mode, and adjusting the operation state of the air conditioning equipment according to the third operation mode.
Specifically, when the human body is in the second heat state, namely the human body is in a hidden sweat releasing state, and the relative humidity of the surface of the human body is less than or equal to 25%, the indoor temperature is further judged, if the indoor temperature is less than or equal to 26 ℃, the fact that the human body is dry and causes discomfort to the human body is shown, and the indoor temperature is not high, therefore, the air conditioning equipment can be controlled to enter a sixth operation mode, namely, the humidifier is controlled to be started, the relative humidity of the indoor air is increased by utilizing the humidifier, the moisture diffusion speed of the surface of the skin is further reduced, the relative humidity of the surface of the skin is increased, and the thermal. If the indoor temperature is higher than 26 ℃, the skin is dry, which causes discomfort to human bodies, and the indoor temperature is higher, therefore, the air conditioning equipment can be controlled to enter a third operation mode, namely, the air conditioner is controlled to be set to be in a refrigeration mode, the indoor temperature is set to be 26 ℃, and meanwhile, the humidifier is not started. The air conditioner is set in a refrigeration mode, so that the ambient temperature can be reduced, the skin surface temperature and the skin moisture diffusion speed are reduced, the relative humidity of the skin is increased, and meanwhile, the indoor temperature is set to be 26 ℃ for preventing the indoor temperature from being too low and influencing the human health.
Further, when the human body is in a hidden perspiration state and the relative humidity of the surface of the human body is more than 25%, the air conditioning equipment is further adjusted through the following steps:
step S10421, judging whether the relative humidity of the human body surface meets a second relative humidity condition; if yes, the air conditioning equipment is controlled to enter a third control mode.
The second relative humidity conditions were: the relative humidity of the human body surface is more than or equal to 45 percent.
Step S10422, determining whether the indoor temperature is less than or equal to a third preset temperature.
In the embodiment of the present invention, the third predetermined temperature is 20 ℃.
And step S10423, if yes, outputting a fourth control signal, controlling the air conditioning equipment to enter a fourth operation mode, and adjusting an operation state of the air conditioning equipment according to the fourth operation mode.
In the embodiment of the invention, the fourth operation mode is that the air conditioner is set to be a heating mode, the indoor temperature is set to be 20 ℃, and the humidifier is not started.
And step S10424, if not, outputting a fifth control signal, controlling the air conditioning equipment to enter a fifth operation mode, and adjusting the operation state of the air conditioning equipment according to the fifth operation mode.
In the embodiment of the present invention, the fifth operation mode is: the air conditioner is set to a dehumidification mode, and the humidifier is not started.
Specifically, when the human body is in a second hot state, namely the human body is in a hidden perspiration state, and the relative humidity of the surface of the human body is greater than or equal to 45%, whether the indoor temperature is less than 20 ℃ is further judged, and if the indoor temperature is less than or equal to 20 ℃, it is indicated that the skin is moist and the indoor temperature is low, so that the human body is not hot and comfortable, at the moment, the air conditioning equipment can be controlled to enter a fourth operation mode, namely the air conditioner is set to be in a heating mode, the indoor temperature is set to be 20 ℃, and the. The environmental temperature is increased through air conditioning heating, so that the skin surface temperature and the moisture diffusion speed are increased, and the relative humidity of the skin is reduced; and in order to prevent the indoor temperature from being raised too high to affect the human health, the indoor temperature is set to be 20 ℃.
When a human body is in a hidden perspiration state and the relative humidity of the surface of the human body is less than 45%, whether the indoor temperature is less than or equal to 20 ℃ or not is further judged, if the indoor temperature is greater than 20 ℃, the skin is wet, so that the human body is hot and uncomfortable, the air conditioning equipment can be controlled to enter a fifth operation mode, namely the air conditioner is set to be in a dehumidification mode, and the humidifier is not started. The relative humidity of indoor air can be reduced through dehumidification by an air conditioner, so that the diffusion speed of moisture on the surface of the skin is increased, and the relative humidity of the skin is reduced.
Further, if the relative humidity of the human body surface does not satisfy the first relative humidity condition and does not satisfy the second relative humidity condition, then: outputting a second control signal to control the air conditioning equipment to enter a second operation mode; the operating state of the air conditioning unit is adjusted according to the second operating mode. Specifically, when a human body is in a hidden perspiration state and the relative humidity of the surface of the human body is between 35% and 45%, the human body feels comfortable, and air conditioning equipment does not need to be started, namely, both an air conditioner and a humidifier are turned off.
It can be understood that, in the embodiment of the present invention, the detected indoor temperature, the detected indoor relative humidity, and the detected temperature information of the human body surface are all real-time data detected at any time. Since the human body thermal regulation is a cyclic process, the method for controlling the air conditioning equipment based on the environment and the body surface temperature and humidity provided by the embodiment of the invention is also a cyclic control process, and the human body thermal regulation period is about 15 minutes, so the sampling frequency of the sensor is less than that of the human body thermal regulation period, and the sampling frequency of the sensor can be set to about 10 minutes, therefore, the method for controlling the air conditioning equipment based on the environment and the body surface temperature of the embodiment of the invention repeatedly executes the steps S101 to S104 every about 10 minutes.
Furthermore, the air conditioning equipment control method based on the environment and the body surface temperature and humidity can also control the air conditioning equipment to enter a first operation mode, wherein the first operation mode is manually controlled, the control mode of the air conditioning equipment can be selected in the specific operation process, and when the control mode is selected as the manual control mode, the operation parameters of the air conditioning equipment and the humidifier are directly set manually, and the operation states of the air conditioning equipment and the humidifier are directly adjusted manually. When the automatic control mode is selected, the adjustment step (step S101 to step S104) can be entered.
It can be understood that in the existing scheme, the air conditioner can be controlled by monitoring the heart rate of the human body, however, in the actual indoor environment, the influence of factors influencing the thermal comfort of the human body, such as the indoor environment, the thermal resistance of clothes of the human body and the like, on the heart rate is not obvious, the human body is mostly in a low activity intensity state, and the heartbeat is stable and has no obvious fluctuation; moreover, different people in a stable state have certain differences in heart rate conditions due to different constitutions, so that the heart rate conditions cannot effectively reflect the heat balance state of the human body. The temperature and relative humidity of the skin surface are comprehensively influenced by factors such as human activity intensity, indoor environment, clothes thermal resistance and the like, so that the temperature and relative humidity of the skin surface can objectively reflect the heat balance state of a human body, and the effect is better when the temperature and relative humidity is used as an evaluation index of the thermal comfort state of the human body. Therefore, the invention can effectively obtain the relative humidity information of the human body surface by utilizing the indoor temperature, the indoor relative humidity and the temperature information of the human body surface which are obtained by the indoor temperature sensor, the indoor relative humidity sensor and the human body surface temperature sensor, thereby realizing the judgment of the human body heat balance state, and integrating the indoor temperature, the indoor relative humidity, the temperature information of the human body surface and the human body heat balance state information, controlling the operation mode of the air conditioning equipment in real time, automatically adjusting the operation state of the air conditioning equipment, thereby achieving the purposes of improving and automatically maintaining the comfort level of the indoor environment and reducing the energy consumption of the air conditioner operation.

As shown in fig. 2, the control device may include:
and a detection unit 10 for acquiring indoor environment information and temperature information of a human body surface through the first detection device and the second detection device.
In the embodiment of the invention, the indoor environment information comprises indoor temperature and indoor relative humidity, wherein the indoor temperature and the indoor relative humidity are both indoor real-time temperature and indoor real-time relative humidity detected by the first detection device at any moment.
